Summary0005530: add replay protection to TCP communicator
DescriptionAs TCP is always bi-redirectional, we can easily add some weak form of replay protection by simply adding a nonce to the KX and requiring that the nonce is sent back. To avoid increasing latency on the initial handshake (and knowing that the first bytes sent will be CORE/CADET KX in all likelihood anyway) we would then simply require that after N bytes the nonce is played back to us.
